I just purchased a popular PURE NMN supplement on Amazon with 200mg per capsule. I've been taking 400mg per day for about 3 days, and was going to work my way up to 1000mg.
Today, I took 600mg and experienced a FULL BLOWN niacin FLUSH that lasted an hour. It was like I had sunburn all over by body. This occurred about 2-3 hrs after consuming 600mg.
Has anyone ever experienced this on NMN? I know this is a common occurrence with Niacin, and it's happened to me in the past when taking too much Niacin. I've also taken Niacinamide (NAM) in the past at 500mg/day and never experienced flushing, but this is the first time I've ever taken a pure NMN supplement.
So can NMN cause flushing, or did I get a bogus product tainted with niacin?
